Key Takeaways
- Paid placements in AI search results are real and available today, but each platform works very differently
- Microsoft Copilot is the most accessible AI ad placement for most advertisers and is already built into your existing Microsoft Advertising campaigns
- Google AI Overviews and AI Mode serve ads through Performance Max and AI Max for Search campaigns
- ChatGPT has opened its ad platform in the US, but costs are high and measurement is limited
- Perplexity abandoned its advertising program entirely in early 2026
- Claude (Anthropic) has stated publicly it will never run ads
The question we get asked more than any other right now is some version of this: can I advertise where AI is giving the answers?
The answer is yes. But how you do it, what it costs, and how well you can measure it looks completely different depending on which platform you are talking about.
Here is a straightforward breakdown of every major AI search surface in 2026, how advertising works on each one, and where we recommend most advertisers put their attention first.
What Does "Advertising on AI Search" Actually Mean?
When people say AI search, they usually mean one of a few things: Google's AI Overviews and AI Mode, Microsoft's Copilot, or standalone AI tools like ChatGPT.
Each of these surfaces answers questions differently. And each one handles advertising differently too.
The short version: Google and Microsoft have integrated AI ads directly into their existing advertising platforms. ChatGPT has launched its own ad program. And some platforms, like Perplexity, tried advertising and walked away from it.
Google AI Overviews and AI Mode
Google's AI generated answers now appear at the top of many search result pages, and yes, ads do appear within them. But you cannot directly target AI Overviews. Google decides whether your ad appears there based on your campaign quality, relevance, and bidding.
The campaigns that currently qualify for AI Overview placements are Performance Max and AI Max for Search. Standard Search campaigns do not qualify for AI Mode placements yet, though Google has indicated that broader eligibility is coming later in 2026.
How to improve your chances of showing up here:
Broad match keywords matter more than they used to. AI search queries tend to be conversational and much longer than traditional keyword searches. Exact match keywords miss a lot of that inventory. Broad match is what helps your campaigns catch those queries.
Product feed quality is no longer optional. If your Shopping feed has vague titles or missing attributes, your ads will not surface in AI results. Clean, detailed product data is a requirement, not a nice to have.
Asset variety helps Performance Max. Google uses your headlines, descriptions, images, and video assets to build ads for AI placements. The more complete and varied your asset library, the better your coverage.
Microsoft Copilot
This is the most accessible AI advertising opportunity available to most businesses today, and it is already built into Microsoft Advertising.
If you are running Search or Performance Max campaigns through Microsoft Advertising, your ads are already eligible to appear inside Copilot conversations. No separate setup. No large minimum spend. You are already part of the way there.
The performance data is compelling. Microsoft research covering late 2024 through mid 2025 shows Copilot placements generating 73% higher click through rates and 16% stronger conversion rates compared to traditional search ads. Customer journeys are also 33% shorter, meaning people move from question to purchase faster inside a conversational AI interface.
Microsoft has also introduced a format called Copilot Checkout, which allows users to complete a purchase directly inside the Copilot conversation without ever clicking to a website. For ecommerce advertisers, that is a meaningful shift in how a transaction happens.
For most advertisers, optimizing for Copilot is the clearest near term win in AI advertising. If you are already running Microsoft campaigns, you are closer than you think.
ChatGPT Ads
OpenAI launched its advertising program in the US in early 2026 and has been expanding access throughout the year.
A few important things to understand before you budget for it:
Targeting is fully contextual. ChatGPT matches ads based on the current conversation topic and past chat history. You cannot select keywords, audiences, or demographic segments. OpenAI controls the matching entirely.
Measurement is limited. Advertisers currently receive aggregate impression and click data. There is no conversion tracking, no demographic breakdowns, and no click through rate data at the individual campaign level. For advertisers used to the precision of Google and Microsoft Ads, this is a significant gap.
Costs are high. CPMs run approximately $60 per thousand impressions, which is roughly six to ten times what you would pay on the Google Display Network. The platform is still maturing and pricing will likely evolve, but right now this is an expensive channel with limited accountability.
Ads reach free tier users only. ChatGPT Plus, Pro, Business, and Enterprise subscribers do not see ads. The addressable audience is real but narrower than the overall ChatGPT user base suggests.
If you have the budget and want to establish an early presence, ChatGPT advertising is worth exploring. For most small and mid sized advertisers, it is not where we would recommend starting.
What About Perplexity and Claude?
Perplexity tested ads through early 2026 and then officially shut the program down. As of today, there are no paid placements available on Perplexity.
Anthropic, the company behind Claude, has stated publicly that it will not run advertising. This is a deliberate product decision. Their Super Bowl ad in 2026 carried the tagline "Ads are coming to AI. But not to Claude." They are not building toward it.
Where Should You Focus Right Now?
For most businesses, the priority order looks like this:
First: Make sure your Google Performance Max campaigns are properly structured to qualify for AI placements. This means a clean product feed, a diverse asset library, and a broad match keyword strategy that gives Google room to find AI queries.
Second: If you are running Microsoft Advertising, confirm your campaigns are set up to serve on Copilot. This is the easiest AI advertising win available today and the one with the strongest performance data behind it.
Third: Keep an eye on ChatGPT advertising. Measurement will improve over time, costs will likely come down, and the platform will mature. Understanding how it works now puts you ahead of the curve when it becomes more accessible.
AI search advertising is not a future thing. It is happening inside your campaigns right now. The question is whether your accounts are built to take advantage of it.
